基于python3 的百度图片下载器的实现代码

自己写了玩的一个小脚本，百度图片下载

import re
import os
import requests
import hashlib

def dowmloadPic(html, keyword):
pic_url = re.findall('"objURL":"(.*?)",', html, re.S)

if len(pic_url) < 1:
return 1

i = 0
for each in pic_url:
print(i + 1, end=',')
md5Str = hashlib.md5(each.encode("utf-8")).hexdigest()

# 抓去链接
oneStr = md5Str + '  ' + keyword + '  ' + each + '\n'
with open('downText.txt', 'a+') as f:
f.write(oneStr)

# 下载图片
# try:
#   pic = requests.get(each, timeout=10)
# except requests.exceptions.ConnectionError:
#   print('链接超时,跳过此操作')
#   continue
#
# kz = os.path.splitext(each)[-1]
# photo = + keyword + '_' + str(i) + kz
#
# with open(photo, 'wb') as f:
#   f.write(pic.content)
i += 1

print('\n')
return 0

if __name__ == '__main__':

word = input('enter a key word:')
page = input('enter the page:')

page = int(page)
page = 1 if page < 1 else page

url = 'http://image.baidu.com/search/flip?tn=baiduimage&ie=utf-8&word=' + word + '&ct=201965323&v=flip'

p = 1
while (p <= page):
print(word + ',第[' + str(p) + ']页：')

pn = (p - 1) * 20
url = url + '&pn=' + str(pn)
result = requests.get(url).content.decode('utf-8')

code = dowmloadPic(result, word)

if code:
print('无相关数据,提前退出程序')
break
p = p + 1

print('程序结束')
